Application filed 'August 22, 1914. Serial No. 853,014.

tain new and useful Improvement in Weit- Replenishing Looms, of which the following is a specification, reference being had therein to the accompanying drawings. l0

rlheteatures of the invention are applicable to shuttle-changing weft-replenishing looms on the order of that shown and described in U. S. Letters Patent No. 945,722,

dated January 4, 1910. However, they arel not necessarily restricted to employment in the particular type of loom illustrated in the said patent, and l contemplate employing embodiments of the principles of the invention in bobbin-changing looms.

@ne feature of the invention consists in means for saving the starting ends of the weft orlling of the stack or reserve weftcarriers occupying the hopper or magazine of a weft-replenishing loom from injury due to cutting orchaling between the portion of 'the said Weit-carriers which contact with one another. A second feature of the invention consists in improved means for insuring that the portion of wett or lling extending from the selvage of the web being woven to an ejected lilling-carrier, otherwise known o the magazine-end of a weft-replenishing loom of the same general character as that shown and described in the patent mentioned above, with certain ot the said embodiments of the improvements applied thereto. The parts are shown in positions assumed by them during the regular running of the loom.

lFig. 2 shows in plan certain of the parts of Fig. l.

Fig. 3 is a rear elevation of the hopper or magazine and parts immediately adjacent the same.

Fig. 4 is a view similar to Fig. 1, but showing certain of the parts in positions assumed by them during the performance of the change operations.

Fig. 5 is a view, partly sectional and looking from the middle of the width of the loom toward the magazine-end of the latter,

showing a second form of embodiment of the improvements in devices for taking care of the trailing weft-end, the trailing-weft catcher being in the position maintained by it during the regular running of the loom.

Fig. 6 is a view similar in character to Fig. 5 but showing certain parts in the positions assumed by them during the performance of the change operations. y

Figs. 7 and 8 are sectional views on the order of Figs. 5 and 6 showing a slightly different construction of the trailing-weft catcher devices.

Having reference to the drawings,-

Only such parts are shown, in addition to those directly involved in the invention, as are necessary to an understanding of the relations and nature of the invention itself.

Portions of one side-frame l of the loom and of the'breast-bea'm 2, the lay-beam 3 and one lay-sword 4 are shown. The* movable front-pla'te of the shuttle-box at the replenishing or magazine-end of' the loom is shown at 5, 6 being the rocker with which the said front-plate is connected, and 7 the motion-transmitting rod through which the said rocker and front-plateale operated to raise and lower the front-plate to open and close said shuttle-box. Only a portion of the said rod is represented. At 8 is indicated the change-shaft which in the patent aforesaid operatively controls the instrumentalities by which the wet-replenishing operations are performed. v At 9 is represented the hopper or magazine for reserve shuttles a?, etc., the said hopper or magazine being mounted, as usual, at one end of the breast-beam. lt has as usual oppositehends which are V- shaped in .cross-section, and thus conform interiorly to* the shape of the shuttle-ends which occupy them. As is Well understood, V

the reserve shuttles that are stacked up in the hopper or magazine rest one on top of out trom the delivery-eyes of the shuttles loop around the said guide and extend thence to the weend holding-pegV l0, and from ltP ig. 3y it will he apparent how the portions of the `starting weit-ends which loop around the said upright, guide a will slide down the said guide as the shuttles descend in the hopper or magazine. il!" hen the hottorn shuttle drops on to the trans ferrer (not now shown) occupying its torward position heneath the hopper or magazine, 'the starting wett-end ot such' shuttles a the said shuttle subsequently is transd to lay the transiter of the shuttle rward taires the said starting wett-end rearward entirely clear oi the guide, as well as of the horizontal portion e of thewire.

The space intervening between the guide a and adjacent edge et the rear wall of the outer portion or end oi the hopper or magazine is suriciently great to permit iree introduction of the weit-end intothe sarne at 'the top, and tree movement of the wettend downward along the guide a as the shuttle descends within the hopper or'ruagazine. Such space may he narrow, or in some cases' it may loe fairly wide as indicated in 3 orp the drawings, In the latter' cases l have found it advisable to employ at the lower end oi the said space means :tor preventing the shuttle which is nent to drop passes helow the bottoni ot the guide a, andl upon the transferrer from rolling or tipping over as it maires its nal drop. ln the present instance such means comprises a guide )i having its acting portion set up close to the shoulder of the said shuttle, so as to prevent the rolling or tipping from taking place, there heing sudicient distance between the said acting portion of the said guide it and the adjacent portion of the wett-end guide o to permit the weft-ends to'pass downward freely between the two guides. This guide It for the shuttle-ends is mounted adjustahly in position to enable its worlring position to he varied as may happen to he required in practice. 'lo this end, it is furnished with an elongated stem passing through a hole at the lower end of a supo porting arm c' that is mounted by means ot a collar Il; upon the supporting rod 11 i'or the hopper or magazine. The arm t' is lined in the required position upon the supporting rod ll hy means ot clamping screws mi, m, providing for securing it in the desired angular position upon the rod, that is to say toward or from the bottom shuttle occupying the hopper or magazine, and also in the required position longitudinally of the rod. The stem of the guide it is adjustably held in place in the hole or socket which it occupies by means of a clamping screw n, this screw providing for adjustment of the guide k in the direction of the length ot the shuttles. The stem may he rotatably adjusted in the said hole or socket to set the acting portion of saidguide forward or rearward as required.

rllhe two ends of the hopper or magazine are mounted upon the supporting rod l1 by means of ears 9a, 9', projecting from them and having transverse holes therethrough enabling them to he titted upon the rod, and

the hopper or magazine is held in adjustahle position lengthwise of the said rod hy means of collars le, 9b, held lined in position upon the rod hy clamping screws m, m. As the reserve shuttles descend in the hopperor magazine and tne starting weitends slide down the guide a., the portions et such weit-ends that entend from the said guide to the weit-end holder l0 pass down between the rod il and the hopper or niagazine, in iront of such rod. As a shuttle is transl-erred from the hopper or magazine to the lay, its starting weit-end becomes entended rearward beneath the rod ll and thereloy hent partly around such rod. When the `just-transierred shuttle is rst'piclred across the loom the inward movement thereoit draws its starting wett-end inward along rod ll until it up against the ear 9a at the inner end oi? l hopper or magazine. ln the inward mov it ot the said starting werpt-end along the rod -l it is dehected out oi engagement with the collar 9b hy meansA of a guide p that entends outward from 'the adjacent hopper-support lll, with its free extremity inclined tard and rearward to such height with. rererence to the hoppersupporting Vrod il that the starting wettend in sliding inward beneath and in oontact with said rod will pass under the said guide p, and he pressed down hy the latter helow and forward of the collar 9b, and consequently clear ot .the latter. l The starting weft-end will then extend downwardrorn the starting weft-end holder l0 to and 'partly/'around guide p, and from' the latter ohliquely downward, rearward., and inward to the adjacent selvage or the weh being woven. As usual, a wett-partei' is employed tor the purpose of severing or parting the said starting weitend close to' the selvage after the first pick of weft laid by.

the fresh shuttle has heen woven in.. An ordinary temple weft-partei' l2 is shown as employed for such purpose. A

To keep the portion of the starting weftend which remains connected with weft-end holder, and which hangs down from the latter, out of the way of a shuttle which is being transferred to the lay, l provide a catcher for such portion or remnant. My present form of such catcher is shown at 0, in the shape of a wire that projects rearward from the hopper-support 14 at the inner end of the hopper or magazine. lts intermediate portion is depressed relative to its slightly elevated rear extremity.

verse slot or harass-a helowwith the trailingend ot wett of the expelled wettfcarrier, and the raising ot the said catcher is designed to insure that the itorward movement ci the said catcher shall present the trailing end properly. to the wett-parten in the construction shown inl .The middle portion ot its length tits between vertical guide-lugs of a guidestand 20 xed upon the breast-beam, the rod or wire bein adapted to play vertically between suc guide-lugs, as well as to move longitudinally forward and rearward between them. The

rear portion of the rod or wire r extendsover the top oi a vertical rod 2l, the upper portion oi 'which passes through a guidehole in the said guide-stand, the rod 2l bein thereby held in vertical position and guide The lower end of the vertical rod 2l is connected with a leverQQ engaging with a rotatable cam 23. While the high parts o the said cani act against the lever 22, the rod 21 is held elevated and thereby gives the trailine-wett catcher-rod or wire 7 its raised position shown'in Fig. l. When the low part oit the cam 23 is presented to the lever 22,

the rod or wire r occupies its lowered po' sition as in Fig. a.

n the construction shown in Figs. 5 and il the vertical movement of the trailing-weft catcher r is due to the employment of a Lnger or secondary arm s that is carriedby `tire arm a or the rockshaft t. This linger or secondary arm projects rearward from the arm a and under the catcher r. ln the rearward position ot the arm and the catcher, shown in Fig. 6, the inger or secondary arm is lowered relative to the catcher,` which occupies its lowered position, with its front end supported by the pivot r4 which connects such end to the arm s, and its rear portion resting upon the bottom of the trans- 'roove a3 in the lay-beam. lWhen the rocshatt t is rocked so as to swing the arm a forward from its position in Fig. 6 to that in Fig. 5 the linger or second'ary arm a is raised under the catcher r and by making contact therewith raises its rear portion by swinging the catcher upward around its pivotal connection r4 with arm s, so that as the rockshat arrives in its torward position the trailing weft-end catcher a occupies the slightly raised position shown in Fig. 5, and thereby resents roperly to the weft-parier the trailing we t-end that it has engaged and moved forward. lhe nger or secondary arm a is lmounted upon arm 8 with provision for adjustment to enable the extent of its lifting action to be varied. ln the present instance such adjustment is eiiected by shift ot the linger or secondary arm in its longitudinally adjusted position. 1

The construction shown in Figs. 'i and 8 diders from that olf Figs. 5 and 6 in the employment of a guide r3 upon the rear side of the lay-beam, through which guide the rear. portion of the catcher r2 extends, and in having the front end of said catcher in sliding engagement with pivot r4. The sliding engagement is provided for by forming the said end .of the catcher with a loop, the length ont which extends upward and downward, the pivot 7'* entering the slot or opening of this loop. This slot or opening per- 85 mits the front end of the catcher r2 to play Y vertically with relation to the pivot r4. When the rockshaft and its arms occupy the forwardly-rocked position in which they 'are shown in Fig. 7, the linger or secondary 'arm eo a supports the catcher r2 in a slightly raised position, with the lower end of `its loop held up against the pivotal stud r4. When the rockshaft and arm are rocked rearwardly into the position shown in Fig. 8, the movement oitq the nger or secondary arm 8 downward awa from the catcher r2 permits the latter to ower until the upper end of its loop rests upon the pivotal stud r4, thereby giving the catcher the required lowered rear position. When the rockshaft and its arm are rocked forward from its rearward position in Fig. 8, the contact of linger or secondary arm s with the underside of the catcher r? operatesto swing the said catcher upward at its forward end, thereby producing the required bodily lifting movement of the catcher as it goes forward in the loom.

rl`he rocking of the rockshaft t is timed to Y occur in the proper time-relation to the 110 ejection of. the spent, or more properly nearly spent, wett-carrier. This is provided or in practice by operatively combiningv it with the devices which indicate for the said ejection or which are concerned 115 in effecting the latter. Since the ejection usually is performed as an incident to automatic replenishment of the working wettsupply, the rockshaft t is in practice indicated into action contemporaneously with 120 the indicating into action of the automatic replenishing mechanism, to operate in proper time-relation in respect of the replenishing operations. In the loom of the patent aforesaid, therockshaft t is the rock- 125 shaft whichv is operated in shipping the driving power of the weaving instrumentalities into action and out of action, and is actuated automatically to rock the same in one direction to unship the driving con.- 130 magazine, and a weft-end holder to which the starting ends of the reserve wefts extend rearwardly through between the weft-carriers in the hopper or magazine, of a weftend guide located at the'rear of said weftcarriers arranged to. keep thel said starting ends beyond the portions of the weft-carriers which contact with one another, thereby obviating chafing of the starting ends by the said contacting portions.
